I have been reading a book online (for FREE) for sometime now and it is a very powerful read for the believer. It shows us a lot about this spiritual battle that Paul talks about in the Bible. It's written by a Pastor Yong-Doo Kim out of South Korea. His church group there has these all-night prayer meetings in which they get involved in heated spiritual battles with principalities that continuously manifest themselves. I'll be honest, this book is not for the faint of heart. It has serious depth. But, it's something that we Christians cannot be ignorant of. Demons are real. The battle is against them. After all, they're battling against us. This book should answer a lot of your questions.
